Connections are made with solid Nickel strips, spot welder to each cell. Each cell and each series is tested before assembly. The BMS will prevent over charging and will balance the cells after a full charge.

so by simply gearing down ones electric bike and then spinning fairly fast also as well with half the pressure on ones pedals for example; the corresponding electric motor assist will also be reduced to ones electric bike; this will help to improve, preserve and optimize the electric bike batteries range in miles.

I am in the process of opening a E Bike outfitting business,I have been experimenting with various motor drive systems, hub direct drive motors, hub gear drive, and at last a mid hub drive. I’ m 68years old my first attempt is 1000 w 48 v 15 ah it’s on a Schwinn MTB I’ve put about 750 miles since May of this year , I ‘d like to try a good peddle assist system as mine dose not work properly and the twist throttle has looped me a couple of times, I use the lowest assist level option, on a recent ride I was able to squeeze 62.5 miles out of full charge with the big hub drive, by just nearly cracking the throttle

Before explaining why, let’s make clear what we mean by an electric bicycle. These are not mopeds or motorcycles, but bicycles that can be pedaled with or without an assist from an electric motor. They’re sometimes called “pedelecs” or “pedal assist” bicycles because in Europe the boost from the motor only kicks in if you pedal; in the U.S., most e-bicycles also come equipped with a throttle to turn on the motor without any pedaling required. Riding an electric bike feels a bit like riding a conventional bike with a brisk wind at your back; the motor helps you go faster and climb hills, but it’s not the primary source of propulsion. Unlike mopeds or electric scooters, e-bicycles are typically permitted on bike paths, and they can’t travel faster than 20 mph.

Some assembly of your new electric bike may be required. Often, this merely involves attaching the front wheel, but assembly chores are sometimes more complex than that. Several manufacturers provide instructional videos to help owners with the task of e-bike assembly.

This aluminum commuter bike is all business, but it’s one of the most versatile e-bikes available. With a Bosch Performance Speed motor housed around the bottom bracket, the center of balance is lower for stability, comfort, and control, even at speeds up to 28 miles per hour. It makes errands easier and won’t stand out when locked in front of a building, thanks to a low-key, matte black paint scheme. And if you ride at night, Super Nova headlights illuminate your way for safety at high speeds.

Where will you Go! Go to work. Go to the beach. Go to the store. Go further. Go somewhere you’ve never been before. Wherever it is, Electra’s Bosch-powered Go! e-bikes make it easier, faster and way more fun to get there. You can ride like the wind without breaking a sweat. They’re simple, intuitive, capable and comfortable. We’d venture to guess you’ll be spending a lot more time on two wheels from now on. All you have to do is get on and Go!

More powerful pedelecs which are not legally classed as bicycles are dubbed S-Pedelecs (short for Schnell-Pedelecs, i.e. Speedy-Pedelecs) in Germany. These have a motor more powerful than 250 watts and less limited, or unlimited, pedal-assist, i.e. the motor does not stop assisting the rider once 25 km/h has been reached. S-Pedelec class e-bikes are therefore usually classified as mopeds or motorcycles rather than as bicycles and therefore may (depending on the jurisdiction) need to be registered and insured, the rider may need some sort of driver’s license (either car or motorcycle) and motorcycle helmets may have to be worn.[14]

Lithium manganese batteries are used in the latest Nissan Leaf electric car. It’s claimed they generate more power and last longer. The new Leaf has double the range of its predecessor, but we’ve seen these batteries in very few (and very expensive) e-bikes so far.

Like electric cars, electric bicycles are manufactured by a mix of startup companies and established players, including Schwinn, Trek, and Giant. Industry executives cite several reasons why e-bicycle sales are poised to take off in the U.S. Most important is the fact that more Americans than ever already bike to work, and that cities and towns are building infrastructure to accommodate them. According to the League of American Bicyclists, bike commuting grew by 47 percent nationally between 2000 and 2011, and it grew by 80 percent in communities designated as “bicycle friendly” by the league. Cities including New York, Chicago, Washington, and Los Angeles are building dedicated bike lanes, like those found in northern Europe, to make commuting safer and easier.

China is the world’s leading manufacturer of e-bikes, with 22.2 million units produced in 2009. One of the biggest manufacturers of E-bikes in the world is Geoby. Production is concentrated in five regions, Tianjin, Zhejiang, Jiangsu, Shandong, and Shanghai.[71] China exported 370,000 e-bikes in 2009.[72]

High pedal assist = you feel like superman!  High pedal assist is when you want to get somewhere quickly and with minimal effort.  This could be useful if you want to get to work without sweating too much.  On the way home you could use the low pedal assist to workout the stress of the day.

The Loft™ Go! is perfect for the urban commuter who wants to get around town or to and from work in style with amazing ease. This pedal-assist e-bike is powered by the Bosch Active System and is built to handle the rigors of city streets.

Size: Some electric bikes look a little small, but if you’re going to drive to the edge of the city and ride the last couple of miles, a light, folding model that you can easily throw in the trunk has definite advantages.

All of which raises a question: Can electric bicycles help solve big environmental problems? The industry — which is making a push to expand its sales in the U.S. — says e-bicycles will reduce greenhouse gas emissions, air pollution, and traffic congestion, while enabling Americans, two-third of whom are obese or overweight, to become more active. In Europe and China, most electric bicycles are sold to commuters, although it’s not clear whether they are replacing conventional bikes, mopeds, or cars.

TerraTrikes make great electric recumbent trikes. Here are a few how to tips converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,…

The Easy Motion Big Bud Pro left a fun impression on us. What’s not to like about those chubby fat tires with two electric motors, one in the back and front? Sporting a 350W electric motor in the back and 250W on the front wheel, this was one fun bike to ride. Why two electric motors on an e-bike? Frankly said, it’s not that much different for everyday riding, but the e-bike came alive on gravel and sandy paths. We can only imagine what a little snow and ice would do to raise our adrenaline past the point of silliness. You can read EBR’s excellent review of it here.

Thanks for helping a little Southern California startup become a global company. A company that can not just hang with the big boys, but lead the way. Thanks for helping us stay true to our roots. For embracing innovation. For realizing that style and substance aren’t mutually exclusive.

It’s what’s inside your motor that sets it apart from the rest. Quality parts and assembly We’ve written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer’s direct-drive motor. The bike was crashed and the…

I like having both options. The throttle is great for getting a quick burst of speed, like when going through an intersection. It is also good when you are riding in a situation that requires you to be able to vary your speed quickly. I like the pedal-assist when riding on open stretches of road. On my Pedego Interceptor I can change the pedal-assist mode very easily so if I need to drop down from Super Girl #5 to Modest Mouse #2 I can do that quickly.
